Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric washing machine having a flooding device.

Conventional structure and its problems Generally speaking, when rinsing laundry in an electric washing machine, the amount of water in the water tank changes depending on the amount of laundry.
That is, it is preferable to adjust the water level. For this reason, conventionally, an overflow pipe is placed on one side of the aquarium, and this can be moved up and down using a lever, but since the overflow pipe is equipped with a filter to remove lint, etc. However, the connection between the lever and the overflow pipe, the lead-out structure, and the adjustment structure using the lever are complicated.

Purpose of the Invention The present invention takes into consideration the above-mentioned conventional problems, and aims to facilitate the attachment and detachment of the adjustment knob of the overflow device and to ensure the adjustment structure of the adjustment knob.

Structure of the Invention In order to achieve the above object, the present invention is a water overflow device constructed on one side of the water tank of an electric washing machine, which includes a recess formed on one side of the water tank, and a water overflow device that rises from the inner bottom of the recess. , an overflow hose that can move up and down,
an overflow hose detachably attached to the side opening of the recess;
It consists of an operating body that is combined with the filter plate and moves the overflow hose up and down, and the operating body includes a front plate, a slit insertion piece inserted into a vertical slit in the filter plate, a back plate, and a hose joint. By pinching the V-shaped knob piece provided on the front plate, the elastic claw at one end provided on the back plate can be disengaged from the serrations on the back side of the filter plate and can be operated in the vertical direction. Based on this configuration, the operating body can be easily fixed in position and released from fixed position, and can be reliably combined with the filter plate.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the drawings. In FIG. 1, 1 is the main body, 2 is a washing tub, 3 is a dehydration tank, 4 is a dehydration basket, 5 is a pulsator, 6 and 7 are motors for rotating the pulsator 5 and the dehydration basket, and 8 is a drain pipe. .

The washing tub 2 is equipped with a flooding device 9 on one side. Specifically, this overflow device 9 includes a recess 10 formed on one side of the washing tub 2, a bellows-shaped overflow hose 11 extending upward from the inner bottom of the recess 10, and a filter that closes a side opening of the recess 10. Board 12
and an operating body 13 for moving the overflow hose 11 up and down to adjust the water level. In addition,
The overflow hose 11 has an open upper portion and a lower portion connected to the drain pipe 8 via a suitable water passage member.

FIGS. 2 to 5 specifically show the structure of the flooding device, and the filter plate 12 has claws 14 at the bottom.
It also has hooks 15 on both sides, the pawls 14 are fitted into locking recesses 16 formed on the front edges of the bottom of the recess 10, and hooks 15 are formed on the front edges of both sides of the recess 10. It is locked and fixed to the edge 17. The filter plate 12 has a bag-shaped handle 18 at the upper part of its front surface, and can be attached to and removed from the opening of the recess 10 by using the handle 18.
Further, the filter plate 12 has a vertical slit 19 in the center thereof, and the upper end of this slit 19 opens into an opening 20 located on the back side of the handle 18. A slit 19 is formed on the front surface of the filter plate 12.
Operating body guides 21 made of vertically long ribs are protruded from both sides of the slit 19, and stoppers 22 for preventing upward movement of the operating body 13 are provided on both sides near the top of the slit 19. Water passage holes 23 are provided on both sides of the operating body guide 21, and sawtooth portions 24 are provided in the vertical direction on both sides of the slit 19 on the back surface of the filter plate 12.

The operating body 13 includes a front plate 25, a substantially V-shaped knob piece 26 integrally formed on the upper part of the front plate 25,
A slit insertion piece 27 vertically protruding from the center of the back surface of the front plate 25, a back plate 28 formed at the tip of the slit insertion piece 27, and an annular hose coupling part 29 connected to the back plate 28. It consists of an elastic piece 31 extending from the back plate 28 and having a claw 30 at its tip, and a disengaging piece 26' provided at the tip of the knob piece 26 and corresponding to the tip of the elastic piece 31. Said plate 25
is a bent piece 3 for holding the operating body guide 21 on both sides.
2, and the back plate 28 also has serrations 24 on both sides.
It has a bent piece 33 for holding the side part of. Further, a display section 34 indicating the water level is provided on the surface of the front plate 25.

The operating body 13 is mounted by inserting the slit insertion piece 27 into the slit 19 of the filter plate 12, positioning the front plate 25 on the front side of the filter plate 12 and positioning the back plate 28 on the back side of the filter plate 19. In this state, the claws 30 of the elastic pieces 31 extending from the back plate 28 engage with the serrated portions 24 on the back surface of the filter plate 12 to fix the position of the operating body 13. Hose connecting portion 2 of the operating body 13
9 is fitted and connected to the upper part of the overflow hose 11. The operation body 13 is attached to and detached from the filter plate 12 as shown in FIGS. 6 and 7. That is, the operating body 13 is inserted from the front into the opening 20 at the top of the slit 19 of the filter plate 12 as shown in FIG. 6, and the slit insertion piece 27 is inserted into the slit 19 from above as shown in FIG.
, and push it down to the state shown in Figure 3. Here, the operating body 13 is attached as shown in FIG.
is prevented from slipping upward by stoppers 22 provided on both sides of the upper part of the slit 19.

In the above-mentioned configuration of the water overflow device 9, when adjusting the water level of the washing tub 2, the tip of the knob piece 26 can be adjusted by pinching the roughly V-shaped knob piece 26 of the operating body 13 so that the V-shaped part thereof is sandwiched. A release piece 26' provided in the release piece 26' pushes the corresponding pawl 30 away from the serration 24. Therefore, the operating body 13 can freely move up and down, and with this movement, the overflow hose 11 connected to the operating body 13 is displaced up and down, and the overflow water level is adjusted. A display section 35 attached to the front plate 25 of the operating body 13 displays the water level. The vertical movement of the operating body 13 is performed smoothly because the bent pieces 32 and 33 of the front plate 25 and the back plate 28 hold the sides of the operating body guide 21 and the serrated portion 24. Moreover, the operating body 13 and the filter plate 12 can be easily attached and detached at the time of repair or inspection.

In the above embodiment, the overflow device is the washing tub 2.
However, it may be provided in the dehydration tank 3 and used for rinsing in the dehydration tank 3.

Effects of the Invention As is clear from the description of the above embodiments, the overflow device for an electric washing machine according to the present invention releases the fixed position of the operating body by pinching the knob of the operating body when adjusting the overflow water level in the water tank. The operating body can be slid with the lever, and the overflow hose connected to it can be moved up and down, making it easy to operate, and the structure for fixing and releasing the operating body is simple, especially when it is connected to the filter plate. These structures can be constructed rationally in relation to each other, and have great practical effects.
